well i fixed the throtle problem but now i have a battery charger problem. what am supposed to use to power the charger? I tryed using a car battery charger to power my charger but it didnt seem like it was working properly as i stated above.when i turn the car charger to 6 amps 12 volts my li-po charger just beeps and blinks alot but when the car charger is on 2 amps it seems like its charging but ive charged it for almost 2 hours total but no straight and the battery didnt even try to get warm it just stayed cold so idk if this is because its like 40 degres in my garage or if its not charging right
